Support missing/additional spaces in peerDependency constraints

[tennox]

Some libs have weird missing/additional spacing in their peerDependency constraints, e.g.:
"react": "^15.0.0 || ^16.0.0 || ^17.0.0 ", - https://github.com/gaearon/react-hot-loader/pull/1843/files

and in some cases, pnpm seems to write them into the lockfile with a missing space:
react: ^15.0.0 || ^16.0.0 || ^17.0.0|| ^18.0.0, but the original package.json is normal 😕

In any case, as pnpm works fine, this package should tolerate these syntaxes
